Abstract :
This paper is focused on the design of coplanar waveguide (CPW) stop-band filters implemented by means of shunt connected open split ring resonators (OSRRs). The filters consist on a cascade of transmission line sections, acting as impedance inverters, alternating with OSRRs. Two illustrative examples are provided in the paper: a Chebyshev stop-band filter centered at 3.4 GHz (40% fractional bandwidth), and a Butterworth stop-band filter centered at 6 GHz (50% fractional bandwidth). These illustrative examples point out that OSRRs can be used in shunt connection in CPW technology for the design of stop-band filters with frequency responses following standard approximations.
